Be it known that I, CHARLES E. GIBBS, a citizen of the United States, residing at Manhattan, in the county of Riley and State of Kansas, have invented a new and useful Timer-Brush, of which the following is a specification.

The device forming the subject matter of this application is a brush of the sort used in the timer of a well known and relatively inexpensive automobile.

The invention aims to provide novel means whereby the brush may be turned end for end, thereby doubling the life of the brush. The invention aims, further, to

provide novel means for mounting the brush on the timer shaft.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit ofl'the invention.

In the accompanying drawings V Figure 1 shows in top plan, a device constructed in accordance with the invention;

Fig. 2 is a section on the line 22 of Fig. 1; Fig. 3 is a cross section on the line 33 of Fig. 1; Fig. 4 is a plan of the blank out of which the collar is made; and Fig. 5 is a fragmental elevation showing a slight modification in one detail of the invention.

In carrying out the invention there is provided a rectangular blank 1 made of metal, the blank 1 being slit within its contour, as shown at 2, to provide a tonguev 3 having an opening 4. A slit is formed in one end 6 of the blank, the slit extending inwardly at right angles to the end 6 as indicated at 5. Thence, the slit is prolonged parallel to the end 6 as indicated at 7 and is extended again at right angles to the end 6, as shown at 8, the slit terminating in a portion 9 disposed parallel to the end 6. In one longitudinal edge of the blank 1, near to the end 10 of the blank, a notch 12 is formed.

' The ends 10 G are brought together, as shown at 25 to form a collar 11 adapted to be mounted on a timer shaft, the notch 12 constituting means whereby the collar may be secured to the shaft. The tongue 3 is struck outwardly from the collar, as shown at 14:, so that the tongue is disposed tangentially of the collar, or substantially so. The material which is partially freed by the slit 56-78 is bent outwardly at right angles to the collar 11, as shown at 15, forming a finger 26,-the projection 16 extending circumferentially of the collar.

The numeral 17 denotes a brush, preferably made out of spring metal and provided with buttons 18 at its ends, the buttons being riveted at 19 to the ends of the brush, or being secured otherwise thereto. In Fig. 2 of the drawings, the button 18 is shown as provided with a convexed wearing surface, but, if desired, as indicated in Fig. 5, the button may be in the form of a disk 20. Openings 21 and 22 are fashioned in the spring brush 17 adjacent to each end thereof. V

In practical operation, the finger 26 is extended through one of the openings 21, the projection 16 engaging the outer surface of thebrush, the brush lying in contact with the tongue 3. A fastening device, preferably of the clenched staple type, shown at 23, is extended through the opening 4 in the tongue, 3, to hold one end of the brush on the tongue. Since the openings 21 and 22 are formed adjacent to each end of the brush 17, the brush may be turned end for end and be assembled with the finger 26 and with the tongue 3, either of the buttons 18, therefore, may be brought into position for use, and the life of the device is doubled, consequently.

Having thus described the invention, what is claimed is:-

1. In a device of the class described, a collar provided with an outstanding tongue and with an outstanding finger; a spring brush; and a securing device connecting the brush with the tongue, the finger'being en-' gaged with the brush, the brush having openings adjacent to each end, for the reception of the securing device and the fin- 'ger, to provide for an end for end reversal of the brush.

2. In a device of the class described, a collar fashioned from a blank having a slit Within its contour, the slit defining a tongue, the blank being provided With a second slit extended inwardly from one end of the blank and prolonged approximately parallel to said end of the blank, the blank having its ends brought together to form a collar, the tongue being struck outwardly, tangentially of the collar, and the finger being bent outwardly to stand approxi- 10 mately at right angles to the axis of the collar; and a spring brush carried by the finger and the tongue.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
